INVENTOR ALBERT w. or KEY wns'r, FLORIDA. v

' sreuannonbme BRACKET.

To all whom it may concern Be it known that I, ALBERT W. THOMP- sox, a citizen of the United States, residing at Key Vest, in the county of Monroe and State 'of Florida, 'have invented new and useful Improvements in Signal: Holding Brackets, of which the following is a specification.

My invention relates to vehicle attachments and has particular reference to signaling devices.

The principal object of this invention contemplates the provision of a combined electricallv operated headlamp and whistle 'for vehicles.

A still further object resides in the employment of such means as -will make it the electric current necessary in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim which is appended hereto and forms a' part of this application.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to ractice, and throughout the several views of which, similar reference numerals designate corresponding parts: Figure 1 is a front elevation of the device illustrated in its assembled position on a bicycle-frame. Fig. 2 is a. top plan view. Fig. 3 is a side elevation. Fig. 4 is a detail perspective'view of the bracket employed to mount the deviceon.

eren ce to the means of the bicycle and have 4 illustrated it in that connection in the accompanying drawings, the device may be as readily applied to any other type of vehicle without departing from the spirit of my invention.

Coming now to the descriptlon of the Specification of Letters Patent.

in the order named, the dynamo indicated by the numeral 1 may be of any standard type. In mounted positiomthe dynamo is disposed with the armature shaft in rectangular relation to the periphery of the wheel. ()n the. rear face of the dynamo casing Patented Jan. 18 1916.

formed an internally screw threaded cup 3 member 2 by means of which'lthedynamo is.

attached to the supporting bracket. The

armature shaft of the dynamo is extended beyond the casing of the dynamo and carries at its terminal a beveled drive wheel 3.

This member is keyed to the armature shaft 4 and is disposed for frictional engage; ment with the inner periphery of the ffelly of the wheel.

The supporting bracket consists of a U shaped metallic strap, the arms 5 of the bracket being bowed outwardly adjacent their free ends as at 6 to form grooves adapted to be mounted around the fork of a bicycle. The terminals of the bracket arms are provided with alined perforations 7 wherein is mounted a retaining bolt by the adjustment of which the bracket may be securely held in frictional engagement with the fork of the bicycle. As a means for supporting the dynamo 1 and the whistle 8, I employ a shaft 9 which is loosely journaled in the opposite side of the bracket and is I provided at each terminal with screw threads, the ends being respectively attached, when the-structure is in assembled position, with the cup member 2 of the dynamo and an internally threaded bore provided in the base portion of the electric whistle 8. Encircling the shaft 9 and disposed between the inner faces of the arms 5 of the bracket, is the spiral spring 10, the fixed end of which isinserted in the perforation provided in the bight portion 11 of the bracket and the free portion 12 which is directed upwardly and outwardly from the bracket and is disposed to bear against the ofl'set portion 13 of the lever arm 14: This member 14 is formed integrally with the cup member of the dynamo and is provided with an'orifice adjacent its fixed end where: by it is mounted on the shaft 9 for rotation. From the foregoing disclosure it willbe apparent. that the spring 12 acts to hold the member 3 in engagement with the inner periphery-of the felly of the wheel.

The electric whistle 8 may be of any stand- '2 ard type and'is attached to the bracket in a manner above described. The lamp 16 is also of ordinary structure and is attached 'to the forward portion of the dynamo by the spring ears 17 formed integrally with the dynamo 1 and the bolt and'winged nut 18.

The description of the actual construction and arrangement of the several parts of this invention being thus disclosed, it now wire 27 connecting the switch 26 with the Presuming that the bicycle is in remains to describe the wires and operation of the signal. VVit-h reference to Fig. 6, the lamp 16 is connected to the dynamo by the wires 19 and 20. A snap switch 21 is placed in the circuit for a purpose hereinafter de-- scribed. From the binding post 22 of the dynamo to which the wire is connected leads the 'whistle Wire 23 and from the binding post 24a wire 25 leads to one contact of the switch 26. The circuit is completed by the lamp, the snap switch 21 may be left open and the whistle sounded by throwing the snap switch 26. In this connection it may be said that the location of the switches 21 and 26 is an arbitrary matter and may be disposed on the bicycle handle bars or any part most convement to the individual other rider.

' It will, of course, be understood that the .abovedescription and accompanying draw-- ings comprehend only the general and preferred embodiment of my invention and that variousminor changes in the details of construction, proportion and arrangement of parts may be madewithin the scope-0f the appended claim and without sacrificing any I of the advantages of my invention.

What is claimed is:

A supporting bracket including a bridge having a pair of arms extending therefrom and having their free end portions formed into clamps, a pivot pin extending through said arms adjacent said bridge, a lever mounted upon said pin and having its free end portion bent to extend across said bridge, and a spring mounted upon said pivot pin between the arms of said bracket andhaving one'end portion rigidly secured to said bracket and its free end extending to engage the bent end portion of said lever whereby said spring will yieldably hold said lever in a normal position.
